LiTiP Description:

LiTiP (Life Time
Prediction) is a software tool for the fatigue lifetime prediction of
composite laminates under proportional cyclic loading. The part of the
solution algorithm which concerns stress analysis is based on the Classical
Laminate Theory, while the life prediction is based on the Ply Discount
method.
LiTiP can be used as a low level design tool by engineers and students due
to the following features:
- a complicated laminate lay-up is allowed;
- cyclic proportional loads to the laminate are applied;
- only elastic constants and S-N curves for a UD composite are needed as
input data;
- a fatigue lifetime of the laminate is predicted. The failure sequence of
plies in the laminate is calculated. Stresses and strains in plies,
stiffness and compliance matrices of the laminate after each damage event
are given.
